AI Mechanical Takeoff,
From Drawings to a Priced BoM.
The Takeoff AI reads equipment schedules, services layouts and duct runs straight off the PDF, and returns a counted, classified bill of material with every item traced back to its sheet.
Only AI That Takes Off Mechanical & HVAC
The Takeoff AI traces every diffuser, damper and duct run back to the drawing.

Mechanical Estimating AI That Reads The Whole Package
The Takeoff AI takes the drawing set as it arrives and counts what is on it, whatever condition the sheets are in.
P&IDs
The Takeoff AI reads the P&ID as the logic of the job, counting every valve, instrument, and spec break by type, and never scales a length from it, because a P&ID has none to give.
Ductwork And Air Devices
The Takeoff AI reads duct runs off the plan, picks up fittings and transitions, and counts diffusers, grilles and registers by type and size.
GAs and Isometrics
The Takeoff AI measures lengths off the scaled GA when isos don’t exist yet, tagging each as measured, and where isos do exist, it cross-checks the BOM table against the drawing body.
HVAC Piping
The Takeoff AI reads duct, air terminals, & mechanical equipment off plans, sections, & schedules, and derives supports & insulation as labeled factors you can adjust.
Material Nobody Draws
The Takeoff AI derives gaskets and bolts from joint counts, supports and hangers from spacing rules, and labels all of it, never burying it in the count.
How The Takeoff AI Does a Mechanical Takeoff
From the package landing on your shared drive to a priced bill of material in three steps.
Upload the Mechanical Package
Drop in the whole scope, drawings and schedules together, and The Takeoff AI scans every sheet, reading each title block before it counts anything.
Mechanical Takeoff
It identifies every valve, fitting, flange, weld, equipment item and steel member, then sizes and classes each one against the line list and spec.
Get the Bill of Material
Quantities arrive grouped by system and spec, with supports and hangers derived, and every count links back to the sheet a reviewer can click into.

Frequently asked questions
It turns a mechanical package, P&IDs, line lists, GAs, isos, and the support steel drawings, into priced, counted quantities. The Takeoff AI runs it on industrial work: process piping, pipe racks, platforms, and the full mechanical scope of plants and terminals.
P&IDs, line lists, pipe class sheets, GAs, isometrics, framing plans, and connection details, all as PDFs the way they arrive, clean vectors or rough scans.
Each source is read for what it's authoritative on, the line list as fact, the P&ID as logic, the GA as geometry, and the iso as fab detail, and when two sources disagree, the richer one wins and the conflict gets flagged.
Yes. Gaskets and bolts come off joint counts, and supports and hangers come off spacing rules, all shown as labeled factors you can adjust rather than buried in the count.
Upload the new sheets and see what changed, so you redo the deltas instead of the whole takeoff.
No. The Takeoff AI is built for industrial mechanical work, process piping, equipment support steel, and packages that come with P&IDs, and commercial HVAC takeoff, ductwork, and sheet metal are outside what it reads.
Every number links to the sheet it came from, so you're never defending a quantity you can't source in a bid review.
No. Upload the package as it arrived and The Takeoff AI identifies what each sheet is.
